Unable to divide and reconnect paths in passive skill tree

When 2 paths of weapon sets connect, I cant continue with both nodes as it says (requirements not met) I guess it should work, when in both weapon sets nodes are connected.

From my understanding, the way that PoE2 is currently designed, a tree can't be connected through different weapon set allocations.

I think Demon Form may be the only example in-game right now, but it may be setup to apply to all Transformations with the current design: when you activate Demon Form, you're shifted to a third (unarmed) weapon set. For this third weapon set, the path connected through weapon sets 1+2 would not exist, making your passive tree disconnected.
